| 英文摘要 |
| For the double integrator with an additive disturbance, an integral sliding surface with fractional exponential term is designed motivated by the nested-saturation control approach and integral sliding mode control principle. By using the Haimo''s finite-time stability theory, it is proved that there is no singularity in the assignment of the integral sliding mode. The suggested control design is able to eliminate the influence of the additive disturbance and at the same time, guarantee that the dynamics on the sliding mode surface is finite-time stable. The effectiveness of the algorithm is illustrated by dealing with a DC motor angular velocity control system. |
